because it is in equilibrium
They are just sitting there, moving and changing according to the forces that are acting on them.

All objects accelerate if the forces acting on them are not balanced.
the forces acting on the weight lifter and the weights are balanced because the forces are not moving or changing direction.
Sadly, no matter how long or how intently I keep my gaze fixed above, I seem to be unable to make out either the objects or the forces acting on them.
All objects on earth have the force of Gravity acting on them.
The net force that is acting on an object that is not changing speed is centripetal force that is pulling the object into a circular path. However, just to be clear on this point, while the object's "speed" is not changing, it's "velocity" certainly is, because velocity, unlike speed, has a directional component to it.
Not balanced. The net force acting on the object is not zero.
Yes, gravity is constantly acting on all objects even when they are at rest.
If the forces acting on an object are equal there is no motion (5N->O<-5N). If the forces are unequal there is movement (7N-->O<-5N).
When the forces acting on an object are balanced, they cancel each other out and the result is no change in its motion.Balanced forces have no effect on motion. Unbalanced forces cause acceleration.
In the activity, I recognized the force of gravity acting downwards on the objects, the force of tension in the strings holding the objects, and the forces of friction between the objects and the surfaces they were placed on.
